An alarm can be resilient in doing it's duty, until it is silenced it will keep doing it's job no matter how long it takes. Repeatedly, it will keep doing the same thing over and over again. You would even be the one tired of it's resilience, till you silence it. This kinda makes me remember my brother, he has same similarities with the alarm. When you tell him to remind you of something, he'll do that beyond your expectations. His reminder will force you into doing it if you were having second thoughts.
It's a good traits, it helps keep things in balance. A repeating sound with a purpose.
